Configuring a communication partner with STEP 7
Using the S7-300 system as an example, the following section outlines the steps
you need to take in STEP 7 to configure the system for communication with an
S7-200 system via the associated Ethernet communications processor. The proce-
dure for the S7-400 system is similar.
For the exact configuration steps, please refer to the STEP 7 description (MLFB:
6ES7 810-4CC05-0YX0) or the handbooks for the CP 343-1 and the CP 443-1.
In S7-300 and S7-400 systems, a distinction is made between configured and free
connections. For configured connections, the connection parameters are specified
by the user. In contrast, free connections do not have to be configured in STEP 7.
